Abstract: Embodiments herein describe spectroscopy systems that use an unmodulated reference optical signal to mitigate noise, or for other advantages. In one embodiment, the unmodulated reference optical signal is transmitted through the same vapor cell as a modulated pump optical signal. As such, the unmodulated reference optical signal experiences absorption by the vapor, which converts laser phase noise to amplitude noise like the other optical signals passing through the vapor cell. In one embodiment, the unmodulated reference optical signal has an optical path in the gas cell that is offset (or non-crossing) from the optical path of the modulated pump optical signal. The unmodulated reference optical signal allows removal or mitigation of the noise on the other optical signal.

Abstract: Embodiments herein describe using compressed source material to perform an atomic experiment or an atomic application within a vacuum chamber (e.g., an atom cooling and trapping apparatus). Source material is often refined and sold with dendritic or crystalline surfaces that result in a very large surface area. This surface area increases the likelihood that a large amount contaminants will form on the surface, which is especially true for reactive source materials. To mitigate the risk of contamination, in the embodiments herein the source material is compressed onto a substrate. This changes the material from having a dendritic or crystalline surface to a flat surface, which has a much smaller surface area and thus is less susceptible to contaminants which can, for example, improve the lifetime usage of the source material.

Abstract: Embodiments herein describe peak detection techniques for selecting an absorption line to lock a spectroscopy laser in a frequency reference (e.g., an atomic clock). In one embodiment, an atomic reference is used which has many absorption lines within a relatively small frequency range (e.g., within a gain profile of the spectroscopy laser). The peak detection techniques can evaluate which of these lines a laser can be locked to. For example, the peak detection algorithm can define a preferred absorption line. But if for some reason the spectroscopy laser cannot be locked to the preferred absorption line, the peak detection technique has at least one backup absorption line. By having a set of candidate absorption lines, the peak detection algorithm can identify a suitable absorption line for lasers with different gain regions, or as gain regions change.

Abstract: Embodiments herein describe an atomic sensor that includes a photonic die that outputs optical signals on a top surface. These optical signals can be directed and shaped as needed to satisfy a particular type of atomic sensor. In one embodiment, an atomic source (e.g., rubidium or cesium) is disposed on the photonic chip to emit atoms when heated. A collimator can then direct the emitted atoms along a path that intersects with the optical signals. This intersection can be used to detect motion (e.g., rotation and acceleration) of the atomic sensor.
